SPECIFICATION forming part of Letters Patent No. 607,934, dated July 26,1898.

Application filed December 16, 1897. Serial No. 662,130. (No model.)

To all whom it may concern.-

Be it known that I, LEANDER LEA, a citizen of the United States,residing at Franklinton, in the parish of Washington and State ofLouisiana, have invented certain new and useful Improvements in Flows;and I do declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention has relation to plows; and the object is to provide asimple, strong, and inexpensive plowand means whereby the moldboard ofthe plow may be adjusted to meet certain requirements and the landsideadjusted to give the plow more land.

With this object in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure l is a perspective view of myimproved plow. Fig. 2 is a rear view of the same. Fig. 3 isa detailperspective view of the stock removed from the plow. Fig. 4 is a similarviewof the moldboard. Fig. 5 is a similar view of the spacing-block, andFig. 6 is a longitudinal sectional view through the landside and theparts in advance and to one side thereof.

In said drawings, 1 denotes the plow-beam, and 2 the handles. Thehandles are connected to the plow-beam and project downwardly, and oneat its extreme lower end is recessed, and the end of the other does notproject quite so far down. Arranged between the lower ends of thesehandles is a plate 3, which is clamped in position by bolts 4:.

5 denotes the plow-stock, which has its upper solid end screw-threaded,as shown at 6, and its lower curved end bifurcated to form two members 77, spaced apart by a block 8, having side flanges 9, that rest on thefor ward edges of the bifurcated members.

10 denotes a brace which projects between the upper ends of thebifurcated members and is pivoted thereto by a stud 11. The upper end ofthis brace projects at an angle to its body portion and is provided withan elongated slot 12, through which passes a bolt13.

14- denotes the moldboard of --the plow, which is secured to the stockby a bolt 15,

projecting through the bifurcated members thereof and held in place by anut 16. The straight or landside edge of the moldboard is provided witha longitudinal rib 17, that embraces the side edge of one of thebifurcated members and makes a finished j oint, as well as preventingthe moldboard twisting or turning upon its pivot when not in use.

18 denotes the landside, which is bolted to the lower end of thebifurcated members of the stock and the spacing-block by a bolt 19 andnut 20. This landside gradually increases in thickness from its forwardend to its rear end, which is provided with a countersunk aperture 21.

22 denotes an adjusting-screw having a head that fits in' thecountersunk aperture and the shoulder on the other side of the landside.This screw passes through an aperture on the plate that is securedbetween the handles and also through an aperture in the lower end of thelonger handle-section. A nut 23 is arranged between this plate and thelonger end of the handle and upon the screw. The nuts on the stock 5 maybe loosened, so that the stock will turn in the beam, and by turning thenut 23 the landside may be moved laterally either in or out to give itmore or less land, as may be desired.

When it is desired to move the moldboard vertically, the nut 1 6 isloosened and the moldboard moved up or down along the curved surface ofthe stock. If, however, it is'de- SllGdytO move the stock vertically,the nuts that secure its upper end to the beam are loosened, as well asthe nut that holds the bolt in engagement with the brace, and the partsadjusted. The nuts are then worked home to bind the parts in the desiredadjustment.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof.

Having thus described my invention, what- I claim, and desire to secureby Letters Patent, is-

1. In a plow, the combinationwith the beam,

of the integral bifurcated stock, formed with the cylindricalscrew-threaded upper end of uniform diameter and adapted to beadjustably secured both axially and longitudinally in said beam andhaving its lower bifurcated members spaced apart and secured in thisrelation, a moldboard and a bolt extending through the moldboard and thespaced members, and a retaining-nut adapted to adjustably clamp themoldboard in position, substantially as and for the purpose set forth.

2. In a plow, the combination with the beam, of the integral bifurcatedstock formed with the cylindrical screw-threaded upper end of uniformdiameter and adapted to be adjustably secured both axially andlongitudinally in said beam and having its lower bifurcated membersspaced apart and secured in this position, a block fitted between saidmembers and formed with lateral flanges at its forward end to engage theforward edge of the two members, a bolt for clamping said block inposition, a moldboard formed with a longitudinal rib on its landsideedge, and a bolt for tween the lower ends of said handles, a stocksecured to the beam, a moldboard secured to the stock, a landsidesecured to the lower end of the stock and graduallyinoreasinginthickness from its forward to its rear end, which rear end is providedwith a countersunk aperture, a screw having a head fitted in saidaperture and having a shoulder on the opposite side of the landside, anda nut located between said plate and one of the handles and on saidscrew, for the purpose of moving said screw laterally and adjusting thelandside, substantially as set forth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

LEANDER LEA.
